Question I Choose the correct option.
1.
A pressure gauge attached to a pipe is reading 1.34 m of Hg at a place where the
atmospheric pressure is 10.33 m of water. The approximate absolute pressure at the
mountain is
a. 930 kPa
b. 181 kPa
c. 280 kPa
d. 100 kPa
2. The flow is said to be unsteady and non-uniform when,
The flow velocity is not changing with time but changing with space
b.
a.
The flow velocity is changing with both time and space
The flow velocity is changing with time but not changing with space
d.
c.
The flow velocity is not changing with both time and space
3. The below figure shows a pipe with a circular cross section of diameter D mm on the left
end and a square cross section with side D mm on the right end. Mercury enters the left
end with a velocity 1 cm/s and leaves the right end with a velocity V2. Find V2 (neglect
losses in the pipc).
Cut
Cannot be find since length is not given
b. Cannot be find since diameter is not given
c. 7.85 mm/s
d. 12.73 mm/s
a.
4. 1 kg water is flowing through an inclined pipe at inflow velocity of 20 m/s. The pressure
at the inlet of the pipe is 200 kPa The total energy at the inlet of the pipe is
a. 200 J
b. 196.2 J
c. 981 J
d. 400 J
